A new report from the United Nations’s climate change agency said that plans proposed by countries to meet their goals under the Paris Agreement “fall far short” of what is needed. The report published Friday synthesized updated plans, called nationally determined contributions (NDCs), from countries that are parties to the treaty. It determined that under the plans, countries’ emissions would be 0.5 percent lower in 2030 than they were in 2010. ADVERTISEMENT The Intergovernmental Panel on Climate Change has found that limiting the planet’s warming to 1.5 degrees celsius would require reducing human-caused carbon dioxide emissions by 45 percent by 2030 when compared to a 2010 level.
